3 AnswersMathematics4 years agoNeed help?? :(?
cos 𝜃 = 5/7
Use the Pythagorean Theorem to determine the third side then find the other five trigonometric functions of theta.
Show all of your work and explain where necessary for full credit! (Pythagorean Theorem, sin, tan, csc, sec, cot)
Okay, so I understand the a^2+b^2=c^2 part. I just don't know where to start with solving the five trigonometric functions of theta.

The amount of time t in years required for a certain radioactive material to decompose is given by the following function where R is the mass of the substance remaining after decomposition, A is the original mass of the substance, and k is a constant related to a particular material. Find the time required for 99 grams of a radioactive substance to decompose so that only 33 grams remain if k = -0.163. Round to the nearest tenth of a year.
t = ln R - ln A / k
